I took an OLG of MICH afte we entered NLN. In the past we have set this UGF to be around 7 Hz. My measurement showed a UGF closed to 5 Hz. We have very little phase margin on that side, so I increased the gain by 3 dB to get us back to 7 Hz UGF. Measurement is saved in "/opt/rtcds/userapps/release/lsc/h1/templates/MICH/MICH/MICH_OLG_NOISE_FULL_LOCK_NLN.xml".

The gain increase was placed in lownoise_length_control. Old gain was 2.3, new gain is 3.2.
